Abstract

A combustion system for engines having at least one cylinder (10). The system may e.g. consist of an exhaust duct, an intake duct (20a), a cylinder chamber (30), a fuel injector for injecting fuel into the cylinder chamber (30), a piston (40) performing a reciprocating motion in the cylinder chamber (30), and a valve (70) for intake and one for exhaust. The intake duct (20a) is connected to the cylinder chamber (30) and said intake valve (70) is operative to open and close, respectively, the connection between the intake duct (20a) and the cylinder chamber (30). The crown (60) of the piston (40) is provided with a cavity (50), shaped so as to enhance the generation of tumbling inside the cylinder chamber (30) during the intake stroke and to contribute to the breakdown during the compression stroke inside the cylinder chamber (30). The intake duct (20a) has an intermittent curve coinciding with the direction of the valve (70), where a longitudinal axis (110) of the valve (70) is angled towards the top (100) of the cylinder chamber (30), for generating the tumbling effect inside the cylinder chamber (30).
